<p>PURPOSE:To execute writing and display of a large image screen at a high speed by impressing a scanning signal to the gates of the FETs corresponding to respective picture elements and display signals to the selected sources or drains to execute writing and impressing prescribed display signals to another sources or drains to execute writing. CONSTITUTION:A ferroelectric liquid crystal having a bistable state is held in place between a substrate provided with the picture element electrodes corresponding to the FETs and a substrate provided with a counter electrode, by which a liquid crystal element is constituted. The gates of the FETs constituting the active matrix are connected to scanning electrodes 6 and the source or drains thereof are connected to display electrodes 7. The counter electrode is grounded. The scanning signal is impressed to the electrodes 6 and the display signals are impressed to the selected electrodes 7, by which the display state based on the 1st orientation state of the liquid crystal is written. The prescribed display signals are impressed to another selected electrodes 7, by which the time divided driving to execute the writing of the display state based on the 2nd orientation state is executed. The display of the large image screen with a large number of the picture elements and at the high speed is thus made possible.</p> |
